Once this $35 million upgrade is in place, LIGO will start using something called quantum “squeezed light.” So, what does that mean exactly?
LIGO’s Gravitational Wave Discovery Is Still In Question, But Why? –

“But the ALIGO+ upgrades will be more dramatic. If all goes to plan, LIGO will be able to detect neutron-star mergers that occur within 325 megaparsecs (around 1 billion light years) of Earth, says Ken Strain, a physicist at the University of Glasgow, UK, who leads a consortium of British universities that are expected to receive most of the UK money. That would nearly double the design sensitivity of 173 megaparsecs that LIGO expects to reach before the ALIGO+ upgrade.”
LIGO Receives New Funding to Search for More Extreme Cosmic Events
“This award ensures that NSF’s LIGO, which made the first historic detection of gravitational waves in 2015, will continue to lead in gravitational-wave science for the next decade,” said Anne Kinney, assistant director for NSF’s Mathematical and Physical Sciences Directorate, in a statement. ”
GET READY FOR GRAVITATIONAL WAVES ALL DAY, EVERY DAY
Another strategy to collect more signals is to build more observatories. Detectors in different locations that register the same signal help the researchers confirm that it’s from a gravitational wave. In addition, more detectors provide more coverage of the universe.

Ill get my space surf board
With all due respect, you are very pretty.
What happens if you through a ball of plutonium the size of Jupiter at a neutron star
Why does even a science story talk about " getting a quantum upgrade" , meaning a large boost in funding. When quantum deals with the very small?
Sooo… Then what?
Maren is so beautiful <3
she fine ash
Oh , Hello ! Nukes will be detected ?
What happen if there is an earthquake? Does it interfere and show incorrect readings?
Keep up the great work Maren :)
Super cute, super smart, super articulate, classy and geeky….will you marry me? 💕🥰🤓 I’ve got a MAJOR thing for girls who can explain sophisticated cutting-edge science without missing a beat. You are truly admirable and I am of course subscribing.
When a gravitational wave is detected, can the physicists there gather enough information about it to tie it to a known point in the sky and associate it with light (etc) waves from an event they can take more imaging of using a telescope?
Quantify "subtle"… We're talking about electromagnetism (light) here… What if the "subtle shift" is equivalent to a multiple of the wavelength – then wouldn't a shift (i.e. gravitational wave) be missed since wave-cancellation would still occur?
Or, are the waves measured on a 3D-axis and not a 2D as portrayed in the video animations?
How does the mirror work?
How do you split a single beam off of, and through, a mirror at the same time?
Is this one of those 2-way (see-through) mirrors?
If so, wouldn't the light interact with the metallic (reflective) particles that create the partial reflectivity?
Or, does the beam project onto some sort of edge or hole in the mirror where part of the beam is unobstructed (traveling onward) and the rest of the beam is reflected down the other path?
Lmfao what a pile of shit
Wow you are sexy… I dont know what it is, but we could measure one thing after the other, really slowly
Ha ha ha ha ha ha ha ha.
She looks like Pluto with glasses

My ears turn red toooo
I thought the Heisenberg uncertainty principle was referring to sex after your married
Sorry -I just farted.
If gravity waves have peaks and troughs, does that mean the peaks have repulsive gravity associated with them?
Very very well articulated presentation!
Seeker: One of the most reputed STEM channels.
Seeker's hosts: Cool and eccentric(=special) with a bunch MSc degrees in top reputed universities.
Seeker's comment section: 99% dumb commenters.
Back when it was Discovery's Seeker, the comment section was polish and enthusiastic. Now it's all about stupid jokes.
Does principles of gravitational waves applies to smaller objects like stars, planets, satellites or even asteroids?
Isn't a blackhole just a neutron star with a shroud?
unless you do LIGO experiment in space it wont work cause land masses experience mini earthquakes all the time and thats going to screw up the results
shame they pick up electromagnetic signals….as thats what laser interferometry is for.
They dont pick up "gravity"…they measure em changes.
so of course more will be found…..your science is a delusion…
That’s just space-time wave not a gravitational wave . If gravitational wave have really existed stars probably cannot move around each other.
If you put a black hole in between sun and earth, and you make the sun disappear. The gravitational wave will travel through black hole and reach earth in speed of light, but the sun light will be distorted by the black hole and circulate black hole several times before it leaves black hole orbit and went towards earth. which means the gravity of sun will disappear earlier than sun light. Also, if you put a large body of water or cosmic dust in-between sun and earth, light will slow down, but gravitational wave won't slow down.
Could we be able to detect celestial bodies with gravitational waves?
Ripples in space time. Am I watching star trek? Real life is pretty crazy
I want to know what the moon does to it, what seismic waves do to it, what change in heat causing subtle shrinking and expanding does to it, and what sounds do to it
I like so much the peacfull gravitational waves that come from the soul you could be perfect on Bolivia Chile and Argentina Lithuim and the posibilities on developing bateries for Tesla cheapear and most efficient watch this i travelled in this countries and mostly the people the indians are really lovely peaceful it is in the cities where things are not so good it could be fantastic if you can film too for BBC https://youtu.be/ymW9yIyNNAo

Thanks! But… @0:31: "…about how LEGO works…"?!? ;) 𝓡𝓲𝓴𝓴𝓲 𝓣𝓲𝓴𝓴𝓲.
So whats the difference between a gravitational wave & a shock wave, from multiple sources in the universe?
Thanks for an interesting video.
I love this ligo fairytale. It's one of my favorite stories.
Sabine Hossenfelder says it's B.S. They still haven't confirmed their measurements using electromagnetic measurements…meaning, they never looked out into space and confirmed that the supposed "wave detection" they made came from a detectable source that correlated. I mean…they looked…but the correlation is shaky at best. Gravitational waves travel at the speed of light so if we detect something, it should correlate to a visible event, whether it's in radio or infrared or x-rays…we should see something!?!
You do realize that space has no properties, right? Therefore, it cannot bend or wave, right? There is no "fabric" of space-time! Once you've realized that, watch this:

If you are capable of watching the following video without the fear of betraying your Faith in Einstein, it might give you something to think about, from how Einstein became famous, and why he was canonized, while never receiving a Nobel prize for Relativity, and not even having confidence in his own theories nor understanding why he was idolized. Einstein's fame is clearly more about mysticism than actual science…
Unfortunately, unlearning is harder than learning…
By the way, I have no association with the authors of the video, nor do I support their paradigm or theories on cosmology. I simply agree with what is said in that video.

Is she wearing an Indian fashion outfit !?👍👌
I cant wait for SALIGO++ exclusive
I'm not sure you are explaining the squeezed light correctly. Stop with the drama.
Thanks. Still difficult to get clear path but I get the meaning.
